Baby Boy Diamond Knitted Jumper and Trousers - Blue

This traditional blue knitted baby boys' outfit from Dandelion is a lovely addition to your little one's wardrobe.

Made in Portugal, the two-piece set features a long-sleeved knitted polo top with a classic ribbed collar, three-button front fastening and a diamond knit pattern across the front. Ribbed cuffs and a matching waistband complete the traditional design.

The coordinating blue knitted trousers feature a simple, understated finish, allowing the patterned top to take centre stage.

Lullaby Lane Buying Advice

Is this a two-piece outfit?

Yes. The outfit includes a separate knitted polo-style top and matching blue knitted trousers, giving you a complete coordinated look.

What occasions would you recommend this outfit for?

This is a versatile little outfit that works particularly well for family visits, days out, photographs and everyday wear. The traditional diamond knit pattern gives it a smart appearance without being overly formal.

Is this outfit suitable for cooler weather?

Yes. The long sleeves and knitted construction make it a lovely option for cooler days. Additional layers may be needed depending on the weather.

Can the top and trousers be worn separately?

Absolutely. The blue knitted polo top can be paired with other trousers, while the matching knitted bottoms can be worn with a coordinating top from your baby's wardrobe.

Which size should I choose?

We recommend selecting your baby's usual age size. If your baby is approaching the upper end of a size range, consider the next size to allow additional growing room.

Please note that some of our clothing follows European/Spanish sizing. You may notice that the label shows sizes like 3 months instead of 0–3 months, or 6 months instead of 3–6 months — this is completely normal and reflects the European size standard.

We consider our clothing true to size, so we recommend choosing your little one’s usual size.
